I using a high speed HDMI cable that came with the Oppo and the same thing happens to the front HDMI input. I'm using the beta firmware. I'm not having the same issue when I connect my Roku 3 into my receiver. I emailed Oppo about it and the tech replied back that he has no issue with the Roku 3 and Oppo. I think that my BDP-103 had defective HDMI inputs. Good thing I'm still in the return/exchange time frame, so I'm going to do an exchange.
